To all whom it may concern:

Be it known that l, EUGENE Gr. Banania, a citizen of the United States, residing at Glenwood, in the county ot Mills and State ot lowa, have in-vented certain new and usetul improvements in Foru-Harvester@ oi which the following is a specification.

rl`his invention relates to a corn harvester, of the class adapted to be driven through a held tor removing the ears from the stalls and has for its object to provide a machine tor the purpose which will be durable and free trom complications. 'lhe novel teatures of construction are tully described hereinafter andare specitically pointed out in the appended claim and are illustrated in the accompanying drawing, wherein,

Figure is a plan view ot the machine, parts being removed andv broken away to clearly show constructlon. Fig. 2 1s a view ot the same in side elevation. Fig. 3 is a.l rear vlew ot the machine.

Figs. d, 5, 6, and i' relate to details. lFig. 4l is a sectional view showing the referred mounting tor a pair oi rollers.v tig. 5 is a view showing means tor communicating a rotatable movement trom the operating shalt to a pair ot carriers. Fig. 6 illustrates the mounting ot the tongue on the anle. Fig. 'i' shows a nest ot gears for counicating a rotatable movement to a pair oi carriers trom the operating shalt.

Describing the construction in detail., the

. conventional vehicle-wheels, arie and vedit titl' hicle steering pole are respectively indicated at 6, l' and 8, the arrangement, inthe present instance being, that the machinev is to be moved forwardly tor removing the ears ot corn trom three rows., a movement tor the operating mechanism being derived trom the pair ot main gear wheelsitl which are rigidly secured to the hubs ot the wheels 6.

`Numeral l@ indicates an operating shaitt disposed parallel with and above the aule and revoluble by the revoluble movement oi the wheels 6 since it is provided with a pair ot pinions il in engagement with the gear wheels 2. 'llhe operating shalt as best shown in Fig, 3 has bearings in the heads a ot a plurality ot upright linlvs h, these linlrs having bearin s upon the aule.

ll provide a plurality oit dedecting or alin ing-members l2, i3, it and l5, which project forwardly trom the arie, each consistu ing ot a U-shaped trame i6 having its convened end disposed at the iront, and pro vided with a hood 1l', the width oi the deiiecting members i3 and li and their trame and hoods being nearly equal to the distance between the rows oi' corn, and when the harvester is driven through a held, the dedecting-members being between the rows, the stalks` ot corn will be moved into line be- .tween the adjacently disposed U-shaped trames i6 and their hoods.

The steering pole 8 is preferably of ltshape, and as bestl shown in Fig. l, the inner ends of its arms a are provided with bearing bloclts 18 for a removable mounting on the axle, Said blocks preferably being provided as best shown in F ig. 6, with removable bearing-plates 18', each block 18 being disposed equidistant trom a wheel 6.

Since the harvester must be turned about at the ends oi the corn-rows, the arms a ot the steering pole are each provided with projections 19 which extend in a` bar 2l in engagement with the toothed gear 22 which is revoluble by the steering wheel 23 and its shaitt under control ot a driver or operator, the racl-r-bar being adapted to actuate a roch-lever 2t and a lever 25, these levers being rigidly connected with the stub-axles 26 oit the respective wheels 2'( tor the rear end ot the tongue, said arles having a pivotal mounting tor their inner ends in a cross-plate 28 carried by the tongue., the levers 2d and 25 being connected by a linh 29, and by means ot these parts, the harvester may be guided so that the trames i6 and their hoods will be suitably disposed between the rows.

lin order that the aiming-members i2, i3, it and l5 may be maintained somewhat above the ground in an inclined position, and that their weight and stresses directed thereto may, in part, be sustained bythe litt ith

Miti

lllltlll bearing-blocks 18 of the steering pole, a pair of truss-rods 31 being provided tc project forwardly of the standards for a connection with a pair of cross-bars 32, which are disposed below a frame 16 of each alining-member 13 and 14, truss-rods 33 being also provided to project convergingly and rearwardly Jfrom the standards, said rods 33, at their junction being provided with a rod 34 which is pivotally connected at its rear en-d with an operating-lever 35, a sector 36 being mounted on the steering pole to be engaged by the pawl of said operating-lever, and as described, the alining members may be under control of an operatorto be elevated or lowered,.and also to be maintained a desired distance from the ground. Numerals 32 indicate cross-bars which are disposed adjacent to ther inner ends of the rectilinear arms of the frames 16 for connecting said arms.

Numerals 37 indicate a pair of links, eachV having its inner end pivotally connected with the axle, its outer end being connected wlth a frame 16. cian alining-Inember l2 or 15. Numerals 38 indicate detlectingloops of inverted U-shape these loops being so mounted, at their lower ends that they :rigidly connect the adj'acently disposed frames 16, and by operation of the lever 35, the links 37, standards 30 and all of the frames 16 together with their hoods, may have coincident swinging movements, to disposesaid frames 16 and their hoods at a required distance above the ground.g

In order that the ears ofv corn may be separated from the stalks and may be conducted rearwardly and discharged from the machine, certain mechanism is employed. Numerals 39 indicate rollers arranged in pairs,

. the rollers of each pair being disposed adj acent to each other below the rectilinear arms of the U-shaped frames 16, their front ends having' journaled bearings in the crossbars 32. Thev rear ends of the rollers of each pair are provided with pinions 40 normally in engagement by means of a spring 41, and as best shown in Fig. 1, one of the rollers of each pair is provided with a miter gear 42 in engagement with a miter -gear 43, in

. 'the present instance three of these gears 43 being employed and mounted on the operati ing-shaft 10, and by thisconstruction, when with horizontal fingers Z) arranged to be moved rearwardly upon an arm of a frame 16 for conducting the detached ears of corn to a hopper or slide 45, and through the slide to a transverse carrier 46 movable in a suitable frame consisting of a horizontal part c and inclined, foldable part d, the ears of corn being discharged from the harvester by the carrier 46.

The mechanism for moving the endless carriers 44 consists, in part, of the miter gears 47 which are mounted on the operating shaft 10, in the present instance three of these gears being employed. Each miter gear 47 is engaged by a miter gear 48 having a wrist pin 49 (best shown in Fig. 5), each wrist-pin 49 being mounted in a hanger 56, and each hanger 50 being mounted on one oi' the inclined strips 51 of the machine frame (Figs. 1-5), the wrist-pin 49 being provided with a sprocket wheel 52 on which is mounted a sprocket chain e.

Journaled in each cross-piece 53 of a pair of adjacent frame-stnps 5l are wnstplns o4, 55, 56 and 5f (Flg. 7.), employed 1n series, each being provided with a toothed gear 58, in the present instance one series of these toothed gears being employed for actuation of each pair of endless carriers 44. As best shown in Figs. 3, 5 and Y7 the wrist pin 5.4 is provided with a sprocketl wheel 59 en gaged by the chain e, and it will be understood that a revoluble movement of the operating shaft 10 will result in a revoluble vmovement of the wrist pin 54 on account of the engagement of the chain e 4with sprocket wheels 52 and 59, also that a revoluble movement of the wrist pin 54 will result in the actuation of all of the engaging pinions 58 of a series. The upper ends of wrist-pins 54 and 57 are provided with sprocket wheels 60, and by the construction described the endless carriers of a pair will be moved as before stated for conducting the detached ears of corn from the inclined rectilinear arms of the frames 16 to the slides or hoppers 45. Numerals 61 indicate idler sprocket wheels mounted upon suitable brackets 62 near the'curved front ends of frames 16 for a mounting of the endless carriers 44.

lThe weight of the transverse carrier 46 together with its frame is supported by the steering pole 8. Numerals 63 indicate hangers disposed parallel with the axle below the horizontal part c of the carrier 46. It is ysuitably secured to the steering pole and by means of braces 64 the frame for the carrier A46 and its frames c and d is supported.

lll

tjaaatar rods 77 being employed for connecting the' lever 7l with the clutch 73.

lt will be understood that the function to be discharged by the springs Ll1 is to nor- /mally maintain the rear ends of the rollers together vvith the pinions .40 in engagement, and also to permit one of the rollers 39 of each pair to move transversely upon occa-V sion, to yprevent breakage, if indurate obstructions should enter between the rollers. Numeral 78 (lFig. l) indicates a detent-rod which may have a slidable movement in the block 79 subject to the resistance of the spring 41 to permit the operation mentioned.

While ll have explained the construction in detail, l do not Wish to be understood as limiting myself in this respect and l may change the form,` size and proportion of 'parts as Well as minor details Within the scope of the invention as claimed.

What l claim as my invention is,-

ln a harvester, a main frame, Wheels on which the frame is supported, a supplementary frame hingedly mounted on the main frame, lll-shaped strips placed side by side on the supplementary frame with the closed curved portions disposed forwardly and downwardly to provide flaring avvs and with the sides of the strips separated to provide parallel channels tov receive the stalks, pairs of shafts geared together for rotation in opposite directions journaled at their forward ends Vin the supplementary frame at opposite sides of the channels and having spiral ribs projecting laterally into the channels to engage the stalks, a bearing block on the supplementary frame adapted to receive the upper rear end of one of the shafts and having a guide space cut-away adjacent the bearing portion thereof, said block-also'having a transverse opening beneath the bearing portion, a bearing for the upper rear end of the companion shaft slidable transversely on said guide space, a rod slidable through the opening in the bearing block and having an upturned end to engage the second bearing, and resilient means associated with said rod.

ln'testimony whereof l have affixed my signature in presence of two Witnesses.
